lNFLATlON-VALVE.

SPECIFICATION forrnngpart of Letters Patent No. 654,565, dated July 24,1900.

Application iiled April 18, 1900.

To a/ZZ uffi/m, t may concern.-

Beit known that I, JOHN H. GOSS, a citizen of the United States,residing at Waterbury, in the county of New Haven and State oi'Connecticut, have invented a certain new and useful Improvement inInflation-Valves, of which the following is a full, clear, and exactdescription.

This invention relates to means for supio porting an inflation-valve inor upon the object to which it is applied in such manner that the valveitself, including itsv casing, may be bodily removed from the supportwithout marring either the support or any portion of the valve, andthereby providing for the repairing or replacing of the valve in case ofinjury without disturbing its support or the connection of said supportwith the object to which it is applied. In the patzo ent granted jointly`to myself and Edward O. Goss, assignors to the Scovill ManufacturingCompany, No. 632,218, dated August 29, 1899, is an instance of a tubularsupport of this character.

The present invention is designed especially to furnish a valve supportor fastening for singletube tires, so called, and extensively used onbicycle 'and other Wheels, and which tires are provided with cots toreceive 3o the valve.

' In carrying out my invention I employ in the most specific formacylindrical tube having its inner end drawn in and closed, saving foran opening only sufficient for the pas- 3 5 sage of air, and having itsouter end socketed and screw-threaded internally to receive theination-valve by its casing, and having external circumferential beadsand. longitudinal ridges, the said beads and ridges serving 4o to gripthe cot and resist longitudinal displacement and any tendency of thetube to turn in application and use, all as I will proceed now moreparticularly to set forth and finally claim.

In the accompanying drawings, illustrating my invention, in the severalfigures of which like parts are similarly designated, Figure l is anelevation, and Fig. 2 a longitudinal section, of my improved valvesupport or fas- Serial No. 13,362. KNO model.)

tening. Fig. 8 is a section showing the support or fastening in positionin the tire-cot, the valve itself being in position therein and shown inelevation. Fig. -i is a cross-section of Fig. l, taken in a plane belowthe circumferential beads and looking down.

As is obvious, the drawings show the parts enlarged.

The nsupport or fastening a may be drawn or otherwise produced fromsheet metal in the form of a tube, with its lowerior inner end b closed,excepting for the air-passage c, and the inner end is thus constructedin order to provide for the exclusion of foreign matter in vulcanizingor'otherwise applying a tube to an object. The upper or outer end isprovided with a socket d to limit the descent of the valve proper intolthe support or fastening, and in order to provide an air-tight joint atthis point a packing-ring e may be interposed, and such packing-ring maybe carried by the valve 0r by the support or fastening. The interior ofthe tube is screw-threaded at f to receive the external screw-thread onthe valve proper. The exterior of the tube has one or morecircumferential beads g, and it is also milled or otherwise ridged, asat h and il. The tubular support or fastening thus constructed isapplied in the cot la of a rubber tire or other object Z to be iniiatedsubstantially as shown in Eig. 3 and may be vulcanized therein or causedto adhere thereto or secured therein in any suitable way, and so thatits beads g, which when two or more are used, as shown, are shoulderedin opposite directions, resist longitudinal displacement in eitherdirection, while its milled ridges resist rotation. The outer end of thecot may he surrounded by a wrapping fm, of Wire, a sheet-metal ring, orany other device which will serve to bind the cot and the tube together.

fn. is the casing of the valve, provided with the external screw-thread0 to engage the internal screw-thread f of the support or fas tening andp is the removable valve-cap by which access is had to the valve for intlation and deflation. The valve mechanism contained within the casing nmay be of any approved construction. By valve I mean the complete orfinished article which could be used Without the tubular support.

As already intimated, by the use of this tubular support or fastening,which is made Wholly independent of the valve and its cas- -ing andremains as a fixture in the cot or other medium by Which it is appliedto .the object to be inflated, it is possible to remove and insert thevalve at pleasure, and thus a valve may be repaired or replaced withoutinjury to or attack of any sort upon the support or fastening and theobject to which it is applied.

It has been previously proposed to close the inner end of asupporting-tube for inflation- Valves by means of an applied bushing;but my invention differs from that construction in that my closure isintegral With the tube itself, and, as already indicated, this integralclosure may be made by drawing that end of the tube to form an inwardlyprojecting iiange, or said flange may be made in any other way, so longas it is integral with the body of the tube.

l. The combination with an inflation-valve and its casing, of a tubehaving its inner end drawn in and closed save for an air-passage,

said tube adapted to receive the valve-casing and permit the readyremoval thereof, substantially as described.

' 2. The combination With an inflation-valve and its casing, of a tubehaving an integral flanged inner end, provided with an air-passage, andscrew-threaded internally to engage .detachably the valve-casing,substantially as described.

3. A tubular support or fastening for inflationvalves, provided With apair of circumferential beads having opposite flat or shoulderedsurfaces, substantially as described.

4. A tubular support or fastening for iniiation-valves, having externallongitudinal ridges, substantially as described.

5. A support orl fastening for infiationvalves, comprising a tube, itsinner end closed integrally saving for an air-passage, its outer endsocketed and internally screw-threaded, external circumferential beads,and external longitudinal ridges, substantially as described.

In testimony whereof I have hereunto set my hand thislGth day of April,A. D. 1900. JOHN Il. GOSS.
